Ikorodu, Lagos, Nigeria, situated at 6.6141° N, 3.5153° E, presents a favorable location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than temperature variations.

Seasonal Solar Performance

The solar energy output in Ikorodu remains relatively stable across all seasons, with only minor fluctuations: Spring sees the highest production at 5.37 kWh per day for each kilowatt of installed solar capacity. Winter follows closely with 5.32 kWh/day, while autumn produces 5.21 kWh/day. Summer, interestingly, has the lowest output at 4.46 kWh/day, likely due to increased cloud cover during the rainy season.

Optimal Panel Positioning

For fixed solar panel installations in Ikorodu, Lagos, the ideal tilt angle to maximize year-round energy production is 7 degrees facing South. This slight tilt helps optimize sunlight capture throughout the year, accounting for the location's proximity to the equator and the Earth's elliptical orbit.

Environmental Considerations

While Ikorodu's climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Rainfall: The region experiences a rainy season, typically from April to October, which may temporarily reduce solar output due to cloud cover. 2. Dust and pollution: Urban air pollution and dust from the Harmattan winds can accumulate on solar panels, potentially decreasing their efficiency. To mitigate these issues, regular cleaning of solar panels is recommended, especially during the dry season when dust accumulation is higher. Additionally, installing panels at the optimal tilt angle can help with natural cleaning during rainfall.

Conclusion

Overall, Ikorodu presents an ideal location for solar PV installations. The consistent year-round sunlight and relatively stable energy output across seasons make it a reliable site for solar energy production. With proper installation and maintenance, solar panels in this location can provide a sustainable and efficient energy source throughout the year.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 50 locations across Nigeria. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Ikorodu

Seasonal solar PV output for Latitude: 6.6141, Longitude: 3.5153 (Ikorodu, Nigeria), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 7° South in Ikorodu, Nigeria

To maximize your solar PV system's energy output in Ikorodu, Nigeria (Lat/Long 6.6141, 3.5153) throughout the year, you should tilt your panels at an angle of 7° South for fixed panel installations.

As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.

We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Ikorodu, Nigeria

If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Ikorodu, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
9° North in Summer	13° South in Autumn	23° South in Winter	0° in Spring

Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.

This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Calculate solar panel row spacing in Ikorodu, Nigeria

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Ikorodu, Nigeria.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. Minimum Spacing:
   We add the shadow length to the horizontal space occupied by tilted panels.

This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.

Topography for solar PV around Ikorodu, Nigeria

Ikorodu, located in Lagos State, Nigeria, sits in a region characterized by relatively flat to gently undulating terrain. The area around Ikorodu is part of the coastal lowlands of southwestern Nigeria, with elevations generally ranging from near sea level to about 50 meters above sea level. The landscape is primarily composed of sedimentary rocks and alluvial deposits, resulting in fertile soils that support various forms of vegetation.

The topography of Ikorodu and its surroundings is influenced by its proximity to the Lagos Lagoon, which forms part of the extensive lagoon system along Nigeria's coast. This creates a mix of land and water features, with some low-lying areas prone to seasonal flooding. The terrain gradually rises as you move inland from the lagoon, forming a series of low hills and shallow valleys.

For large-scale solar PV installations, the areas most suited would be the slightly elevated, open spaces to the north and northeast of Ikorodu. These locations offer several advantages for solar energy production:

1. They are generally flatter and more stable, reducing the cost and complexity of site preparation.
2. They experience less flooding risk compared to areas closer to the lagoon.
3. There is typically less vegetation and urban development in these directions, providing more unobstructed space for solar arrays.
4. The slightly higher elevation may offer better exposure to sunlight throughout the day.

However, it's important to note that any large-scale solar PV project would require detailed site-specific assessments. Factors such as local microclimates, soil stability, access to the power grid, and environmental impact would need to be carefully evaluated. Additionally, the rapid urban expansion in the greater Lagos area means that suitable sites may be under pressure from other forms of development, potentially complicating land acquisition for solar projects.
